Selecting middle "item" in scrolling ui

[hollow spear]

Sup! i would want to make, so that element which is on middle of the scrolling frame, would be highlighed

and ofc to change whenever player scrolls in it

How well do you know vector math?

[hazy schooner]

you could access and iterate on all the elements, and then check if the elements are an odd number, and then i guess divide the elements by 2 to get the middle element in some way?

and then highlight the element in your preferred way like colors, or outline etc...

i never really worked with scroll ui's

and i want the middle element to be highlighted, but not of whole frame, just of the part that players is currently viewing

if that makes sense

[hollow spear]

good question!

idk i i explained well

(the things draw in black is the whole scrolling frame)

[hazy schooner]

i see

so you want the middle element to be highlighted based off what the player is seeing in the scroll ui, once he scrolls, the middle element changes and stays in the middle

[hollow spear]

yes

[hazy schooner]

this is quite hard

[hollow spear]

so i should just use something else?

like basic select ui

instead of selecting thro scrolling

It's simple vector math, so I suppose I got my answer

The middle object is the object with a center which is closest to the center of the window

[hollow spear]

how do i get center of window?

i havent worked much with ui's

[hollow spear]

i see, how to get window's center tho?

[mighty wadi]

window center = absolute position + window size / 2
object center = absolute position + absolute size / 2

i litteraly never even used scroll frame
